By mistake I copied the usermanager.npk v6.40.6 to a RB Groove v6.39.2 and when restarting the RB, it was apparently damaged. Now for a few seconds all the LEDs flash and then turn off (at that moment the PC detects disconnection in the Ethernet port), 8-9 seconds later, the same happens; an infinite cycle.
The RB is not detected by the winbox or netinstall. I tried to reset by pressing the button at the bottom and the same thing keeps happening. How can I go back to the previous state? otherwise, how can I access "files" and delete the npk?
